SHOE-TREE.

Specification of Letters Patent.

Patented July 5, 1910.

To all whom it may concern:

Be it known that I, JoHN S. HANSEN, a citizen of the United States,residing at Brockton, in the county of Plymouth and State ofMassachusetts, have invented certain Improvemelits in Shoe-Trees, ofwhich the following description, in connection with the accompanyingdrawings, is a specification, like reference characters on the drawingsindicating like parts in the several figures.

This invention relates to improvements in shoe trees, lasts, and similardevices.

An important object of the invention is to provide a device of thischaracter in which the fore part and the heel part are connected formovements toward and from each other by two movably connected members,and where such connection comprises an improved arrangement of partswhich will be simple in construction, easy of operation, and capable ofadjustment in such manner as to effectively maintain the connectingmembers in position while in the shoe.

WVith this object in view, the invention contemplates the provision ofmeans permitting relative longitudinal, as well as pivotal movements, ofthe two members connecting the fore part with the heel part, togetherwith devices for holding the members against relative longitudinalmovements when adjusted properly for a given length of shoe, and lockingmeans for such devices which is rendered effective when the members areextended to position the tree properly in a shoe, but is renderedinefiective when said members are retracted to remove the tree from ashoe. Preferably, the ole vices for holding the members in adjustedposition comprise a series of ratchet teeth, formed on or carried by oneof the connecting. members, and a pawl supported by a part which is insliding engagement with said member and is pivotally connected with theother-member, the pawl being arranged to engage with the ratchet teeth.Preferably, also, the locking means referred to comprises a portion ofthe pivotally connected member which extends beyond. its pivot andbeneath the rear end of the pawl, and is so formed that it will permitsuch end of the pawl to be depressed to disengage the pawl from theratchet teeth when said members are retracted, or moved toward eachother, but will come in contact with the pawl, move it into engagementwith the ratchet, and hold it there against disengagement when themembers are reversely moved or extended, as upon the insertion of thetree into a shoe.

The drawing illustrates, in side elevation, a shoe-tree embodying myinvention in position in a shoe, the shoe being shown in section, andtheposition of the parts of the tree during its insertion and removalappearing in dotted lines.

In the embodiment of the invention selected for illustration, 1indicates the fore part, which may be constructed of wood, metal, or anyother suitable material. In the rear portion of the fore part a kerf ispreferably formed, to receive the end of a lever 3, which mayconveniently be 0011- nected with the fore part for pivotal movementsrelatively thereto, by a pin, 2, or any equivalent means. The lever 3 isprovided upon one edge with a series of ratchet teeth, 5, and at asuitable point between its edges, with a slot, 4, which latter extendstoward the rear extremity of the lever.

The heel part, 14, of the tree, may, as shown, be formed of rounded, orellipsoidal form, and connected therewith is an arm, 10, having anextended and laterally bent portion, 13, to constitute a handle, and thearm being pivotally connected with a slide 7, by a pm, 11, or the like.The arm 10 is provided with an extension beyond its pivot pin 11, havingone portion of its edge, 15, formed concentric with the pin and anotherportion thereof, 16, cut away to present a cam-like edge the part 16being located nearer to the pin 11 than the part 15. The slide 7 ispreferably constructed with two sides and a bottom portion, and betweenits sides receives the lever 3, which is arranged along the side of thearm 10 and is adapted for adjustment longitudinally thereof. The pin 11,which pivotally connects the arm and slide, also passes through the slot4 in the lever 3, and thereby assists in guiding the lever in itsmovements relatively to the slide, as well as securing the lever, slideand arm, together. A pawl, 9, is pivoted to the slide by a pin, 12, andhas its forward end provided with a tooth which is arranged to engagethe teeth of the ratchet 5, and its rear end located above the extensionof the arm 10, as shown.

In operation, prior to the insertion of the end of the pawl and permit,such end to be depressed to release the pawl from engagement with theratchet. The lever 3 maythen be moved freely, in either direction,

along the slide and arm until the. proper adjustment of the tree hasbeen effected, the fore part and the heel part inserted in a shoe, and:the handle i'18 depressed to straighten the toggle and force saidv partssnugly in position against the toe portion and counter of the shoe. Inthis operation the rotation. 'of-the arm lOabout the pivot 11 will causethe part 1'5 tohengage the rear end. of the pawl and automaticallyeffect the reengage ment of-the pawl with the ratchet.

. Certain features of the tree shown capable of embodiment in astructure wherein the cam surface -16is omitted, togetherwith itsfunction, arenot claimed herein, but are claimed in a co-pendingapplication, Sen

No. 525,358,: filed by meOctober 29, 1909.:

' The invention is notlimited by the details of construction hereinillustrated and described, but such details may be varied and theinvention may be embodied in other forms without departing from theprinciples thereof, as set forth in .the following claims. 1

Having thus described my invention, what I claim as new and desire tosecure by Letters, Patent ,of the United States is l. A shoe-tree,comprising a fore part and a heel part, two'longitudinally adjustabletoggle members connecting saidparts, and

means for maintaining said members in various positions of adjustmentconstructed and arranged, to be'rendered effective when the toggle isstraightened and to be rendered ineifective when thevtoggle is broken.

2. r A shoe-tree, comprising a fore part and a heel part, a connectionbetween said parts including two pivotally connected members arrangedfor relative longltudinal ad ustment, means for maintaining said membersin adjustedposition, and a device controlled by the movement of saidmembers about their pivotal connection for locking said means againstmovement.

A shoe-tree having, in combination, a

fore part and a heel part,a member connected with each of said parts, aconnection between said members constructed and arranged to permitrelative pivotaland longitudinal movements thereof, and means controlledby the pivotal movement of the members to lock them in, adjustedposition.

4:- A shoe-tree, comprising a fore part and a heel part, a memberconnected with one of said parts and provided with teeth, amember'connected'with the other part and carrying a pawl to cooperatewith said teeth, means connecting said members for relative pivotal andlongitudinal movements, and means carried by one of the members forholding the pawl in engagement with any oneof the teeth when the tree ispositioned in a shoe, but arranged to permit the pawl to be releasedfrom such engagement when the tree is removed from a shoe.

5. A shoe-tree, comprising a fore part and a heel part, a memberconnected with one of said parts and provided with teeth, a slidemounted adjustable on said member and car- ,rying a pawl to cooperatewith said teeth, a second member connected with the other of said partsand pivotally connected with said slide, said member having a cam-shapedportion constructed and arranged to hold the pawl in engagement with oneof the teeth when the members are extended to position the tree in ashoe but to permit the pawl to be released from such engagementwhen themembers are retracted to remove the tree from a shoe. 7

6. A shoe-tree, comprising a fore part and a heel part, a memberpivotally connected with one of said parts and provided with teeth and aslot, a slide mounted on said member and carrying a pawl to cooperatewith said teeth, a second member connected at one end with the other ofsaid parts and provided at its other endwith a cam to engage said pawl,and pivotal means connecting said second member and slide and passingthrough the slot in the first-named member, said parts being soconstructed and arranged that -when the members are extended to positionthe tree in a shoe the cam will hold the pawl in engagement with one ofthe teeth but when the members are retracted to remove the tree from ashoe the cam will permit the pawl to be released from such engagement. 1

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
